(a) Write the rate expression. (b) Find the rate constant for `{:([A]_(0),[B]_(0),,,"`R_(0)` "Rate" (mol litre^(-1) s^(-1))),(0.1,0.2,,,0.05),(0.2,0.2,,,0.10),(0.1,0.1,,,0.05):}` |

Answer» Rate `=K[A]^(m)[B]^(n)` where `m, n` are order of reaction with respect to `A` and `B` respectively. `K` is rate constant. `:. 0.05=K[0.1]^(m)[0.2]^(n) …(1)` `0.10=K[0.2]^(m)[0.2]^(n) …(2)` `0.05=K[0.1]^(m)[0.1]^(n) …(3)` By eqs. (1) and (2), `m=1` By eqs. (1) and (3), `n=0` `:. Rate=K[A]^(1)[B]^(0)` or `0.05=K[0.1]^(1)` or `K=0.5 sec^(-1)` |
